Most telescopes include finderscopes in their kit, but users can also purchase these finders separately. There are two main types of finderscopes; one provides a direct view, while the other offers an angled view. The appropriate option depends on the type of telescope used; for instance, a finderscope with an erect image is considered better for use with Newtonian reflecting telescopes.
They vary
The visual fields among different telescopes, as telescopes help to accurately identify targets by facilitating the observation process. Some finder scopes come equipped with correcting prisms that invert the image, meaning that the images are oriented correctly upwards, while there are telescopes that do not include such correction, resulting in an inverted image that may cause confusion, especially for beginners.
Telescope finders can have a significant impact on the ease of using a telescope. With the minimum number of searches and adjustments, accurately aligning the telescope becomes an easy task, making the observing experience more enjoyable and successful. In the absence of a finder scope, the observer may face greater difficulties in locating objects at night, which affects the overall experience.
What Do Lens, Magnification, and Focal Length Mean in a Telescope?
The lens or primary mirror is the largest part of the telescope and determines its ability to gather light. The larger the diameter of the lens, the more light it collects, and the more detail is visible. For example, a telescope with a 200 mm diameter lens collects four times more light than a telescope with a 100 mm diameter lens, translating into more precise details in observations. Under ideal conditions, a 100 mm telescope can see stars up to a magnitude of +11.8, while a 200 mm telescope can see stars up to a magnitude of +13.3.
Magnification depends on the focal length of the telescope. The magnification of a telescope is calculated by dividing the focal length of the telescope by the focal length of the eyepiece used. For instance, a telescope with an 800 mm focal length using a 10 mm eyepiece will provide 80x magnification. Controlling magnification is vital as inappropriate changes can lead to undesirable results in image quality.
Ultimately, ensuring knowledge on how to use lenses and mirrors and focal length will enhance the observing experience and contribute to accuracy in focusing. Every telescope observer should have a set of eyepieces with differing focal lengths to achieve the best results under various conditions.
